No, the number of children in a household is not an interval variable; it is a discrete variable. Interval variables have meaningful intervals between values but do not have a true zero point, whereas the number of children can only take on whole number values (0, 1, 2, etc.) and has a true zero, indicating the absence of children. Therefore, it is categorized as a ratio variable, which is a more specific type of quantitative variable.
· Dependent variable ( student's academic achievement ) : It depend on the way that we use it to write the score (if we write it as a letter it will be an ordinal ,but if we write it as number it will be an interval). · Independent variable ( intelligent ) : Interval, · Independent variable ( attention ) : Interval,

Yes, it is possible for one or more of the 16 households to have the mean number of children. The mean is calculated by dividing the total number of children across all households by the number of households. If this total is evenly distributed or if one household has a number of children that aligns with the calculated mean, then that household could indeed have the mean number of children.
There is no interval in a single number.
Yes, if it is the closed interval. No, if it is the open interval.
Four types of intermittent schedules of reinforcement are fixed ratio, variable ratio, fixed interval, and variable interval. Fixed ratio schedules provide reinforcement after a set number of responses, while variable ratio schedules provide reinforcement after a varying number of responses. Fixed interval schedules provide reinforcement after a set time interval, while variable interval schedules provide reinforcement after a varying time interval.

Depends, if you're looking for the raw score then you have a continuous ordinal variable. If you have range of number of car accidents, then you have an interval variable.
The average number of children per household in the United States was 2.
The average number of children per household in the United States was 3.
Neither. It is a discrete variable.
IDK but the average number of children per household now is 2.3
On the contrary, the number of children in a given family is a discontinuous variable. If you were talking about averagenumbers of children, that would be a continuous variable because the average could be any number, 2.3987, or 3.07428, and so forth. But in a given family, the number of children is always an integer. You can have none, or one, or two, or three, etc., but you cannot have two and a quarter children. So the variable is not continuous.
Fixed-ratio schedule - reinforcement depends on a specific number of correct responses before reinforcement can be obtained. Like rewarding every fourth response. Variable-ratio schedule - reinforcement does not required a fixed or set number of responses before reinforcement can be obtained. Like slot machines in the casinos. Fixed-interval schedule - reinforcement in which a specific amount of time must elapse before a response will elicit reinforcement. Like studying feverishly the day before the test. Variable-interval schedule - reinforcement in which changing amounts of time must elapse before a response will abtain reinforcement.
